Specification of Letters Patent.

Patented Apr. '7, 1914.

Application filed August 28, 1912. Serial No. 717,534.

To all whom it may concern Be it known that I, BENJAMIN Gr. CAMP- BELL, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Closet- Valves, of which the following is a specification.

The hereinafter described invention relates to an improved closet flushing device and valve for controlling the same, and more particularly to a device of the above char-1 acter adapted to be controlled by the oc-i cupancy of a closet seat, and has for its prin-j cipal object to provide a device of the above character that upon the occupancy of a closet seat a sufficient quantity of flush wa ter is stored under service pipe pressure in. a suitable receptacle, and upon'the occupant leaving the seat the flush water stored under pressure is permitted to enter the closet bowl and flush the same.

Another object is to provide a structure operated in the above manner and which is also capable of being manually operated to flush the closet bowl while the seat thereof is occupied.

A further and important object is to provide a valve mechanism for the above type of device which is capable of being readily removed from its casing that the valves and corresponding seats may be ground, replaced or adjusted as required.

With the above mentioned and other objects in view, the invention consists in the novel construction and combination of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

To fully comprehend the invention, reference should be had to the accompanying drawings, disclosing one form of my invention, wherein Figure 1 is a view of my complete device mounted in operative relation to a closet bowl. Fig. 2 is a vertical central sectional view of my improved valve, the casing surrounding the same and the reservoir in which the flush water is stored under service pipe pressure the various parts of the valve Referring more particularly to the drawings, the reference numeral 1 indicates a suitable oblong valve casing preferably cylindrical in shape, provided in its side wall adjacent its top edge with an opening 2 which connects with the service pipe of the usual water main, and provided adjacent its lower closed end with an opening 3 which connects through the flushing pipe 4: with the usual closet bowl 5. Provided in the casing 1 between the openings 2 and 3 is 1 another opening 6 which communicates with a suitable reservoir 7 which is preferably in the form of a closed chamber and is provided at its top with a small air inlet opening 8 normally closed by a suitable spring pressed valve 9 positioned on the inner side of the reservoir.

The valve casing is provided on its inner surface with inwardly projecting annular flanges 10 and 11, positioned respectively immediately below the opening 2, and between the openings 3 and 6, as in Figs. 2 and 3 of the drawings, and each is formed with the respective downwardly beveled inner peripheral edge 12 and 13. The edge 12 of the flange 10 is adapted to receive and seat the correspondingly beveled edge of an annular ring 14, from the underside of which depends a frame 15, the lower end of which is provided with an opening 16 through which reciprocates a valve stem 17. The inner edge of said ring 1 1 is inwardly and downwardly beveled and is adapted to receive and seat a suitable spider plate 18, which is provided in its center with a suitable aperture through which extends the valve stem 17 and from the upper side of said spider extends a suitable frame 19, which is of sufficient height that the upper edge thereof is engaged by the underside of a suitable casing cover 20, which when it is secured in position retains the spider 18 and annular ring 14 in position. The frame 19 is provided with a suitable opening 21 through which the upper end of the valve stem 17 extends, the valve stem also extending through an opening22 in the casing cover 20, said opening being provided with a suitable packing gland to prevent the escape of the water from around the valve upwardly in contact with the spider plate 18 to close the apertures therein and prevent the entrance of water into the reservoir, by the action of a coiled spring 25 surrounding the valve stem 17 and interposed between'the underside of the inlet valve plate 23 and the upper surface of the lower portion of the frame 15.

Screw-threaded to the lower'end of the valve stem 17 are suitable arms 25, curved downwardly at their outer ends, and carrying an annular rlng or valve seat 26, formed with correspondingly beveled inner and outer edges 27 and 28,-the edge 28 adaptedv to seat on the beveled edge of the annular flange 11 and positioned within the annular ring or valveseat 26, is a suitable disk valve 29 carriedon the upper end of-annular stem 30, the valve having its peripheral edges beveled to seaton the inner edge 27 of the ring, and said disk is of a size "sufficient toi be retained within the valve seat 26 and close the opening therein.

From the above construction it will be observedthat when the valve plate 23 is in its uppermost position, closing-the openings in the spider 18 and shutting off the flow of water from the service pipe into the reservoir 7 that the ring 27 and plate 29 arein their uppermost'position, opening the communication from the reservoir 7 to the closet bowl 5 and that when the valve stem} 17 is forced downwardly against the action of'the spring 25 and the plate 23 is in its lowermost position away from the spider 18,

"the plate 29 and the ring 28 are in their lowermost position and the flush water is admitted from'the service pipe through the opening 2 into the casing 1, and is forced through the openings in the'spider 18 under? service 'pipe pressure into the reservoir 7 where it is stored until such time as pres-g sure'is released on the valve stem 17 or the; valve plate 29 is operated in a hereinafter described manner.

The valve stem'30 extends through a suit-a able'ope'ning in the base of the casing 1 and is surrounded by 'a suitable packing gland 31 which prevents the leakage of water around said stem. Anoperating handle 32, 'fulcrumed as at 33, to a bracket 34 projecting downwardly from the casing 1, is pivotally mounted at its inner end, as at 35, to thelower end of the valve stem 30, and the outer end of saidhandle extends'outwardly adjacent the side of the closet bowl, and is adapted to 'be operated to flush the bowl when the closet seat is occupied, the valve being normally seated by the tension of a coiled spring 36.

Extending upwardly from the upper rear surface of the casing 1 are parallel spaced arms 37, provided at their upper ends with suitable angularly arranged, downwardly opening slots 38, adapted to receive a transverse bar 39 projecting from the rear of a closet seat 40, of the usual construction, The closet seat 40 rests on the upper end of the valve stem 17, and when unoccupied is in spaced relation over the closet bowl 5,

the force of the spring 25 being sufficient to maintain the seat in its elevated position when unoccupied. The seat may also be depressed to operate the flushing valve, through the medium of a pivotally mounted floor plate 411 which is connected with the rear portion of the seat 40 by a flexible member 42.

It will be apparent that when the closet seat 10 is occupied, the inlet valve 23 will be unseated, and the outlet valve comprising the ring 26 and the valve plate 29 will be seated, this position of the valves permitting the water to enter the reservoir 7 under service pipe pressure, the water as it enters the reservoir compressing the air contained therein to the same pressure as the pressure of the water in the service pipe. When the closet ,seat is occupied and it is desired to flush the bowl without rising from the seat,

it is only necessary to force the handle 32' downwardly which through the various connections will force the valve plate 29 upwardly, and the valve 23 being in its lowermost position, it will be readily seen that a direct communication is made between the water service pipe and the closet bowl, and that the flush water will enter the bow] under service pipe pressure. When pressure is released on the handle 32 the valve plate 29 will be seated within the ring 26 by the action of the spring 36, and any water thatmay have been drawn from the reservoir ,7, will be replaced therein under flush water contained in the reservoir will be forced, by the expansion ofthe air in said reservoir, under service pipe pressure into the closet bowl, flushing the same.

Should the air in the reservoir 7 fall be low atmospheric pressure-or should a vacuum be formed in said reservoir at any time when the air therein is expanding to force the flush water therefrom, the valve 9 will be unseated by the vacuum so formed and air will be admitted through the opening 8 to break said vacuum.

Should any of the valves need repairing or become deranged at any time, it is only necessary to remove the casing cover 20, remove the pin from the pivotal point 35 and the entire valve structure may be removed from the casing 1.

From the above description it will be observed that I have provided a valve which is simple in construction, thoroughly eflicient in all of its operations and one which can be operated by the occupancy of the closet seat or operated while seated on the closet seat.
